CNVs and the Creationist Fray

PZ Myers found that the Institute for Creation Research is using a recent Genome Research paper as evidence for design. In the paper, Arizona State researchers studied copy number variations patterns in 30 human and 30 chimpanzee genomes. They found that the species shared duplication hotspots where there tended to be more CNVs. From this, the ICR article says that the researchers "referred to the chromosomal arrangement of CNVs as 'sequence motifs or architectures.' 'Architecture' logically suggests an architect." Myers is incensed, writing:

An architecture does not imply intent or purpose, but they often imply a history. The pattern described — that chimps and humans share some common structural elements in their genomes — is better described as evidence of common ancestry than of well-designed function.
